I can’t agree with your recommendations of Starbound and Starsector. I spent a lot of time with these games trying to figure out why I wasn’t having a good time, and I think in both cases it boils down to the fact their development didn’t fulfill the expectations that the early versions created.
Starbound has beautiful graphics and music and a charming atmosphere, but the gameplay is incredibly dull, the combat is awkward and clunky, your movement abilities are pathetic, etc., etc. For some reason the devs decided to implement a story, and it’s literally the dumbest shit I’ve ever heard. And even though this is a building game like Minecraft or Terraria, you can’t build your ship or any of the boss arenas, all bosses are fought in special levels that are protected from your mining/building tool with a magic forcefield. It’s like the devs didn’t even know what kind of game they were making.
Starsector has the opposite problem, the dev knows exactly how he wants his game to play and implements mechanics specifically to prohibit other playstyles. You want to spend all your skill points on buffs for your piloted ship and play this like a space shooter? Too bad, your single ship will run out of combat readiness and explode. You want to sit back and just command your fleet without getting directly engaged? Too bad, every command you issue consumes a command point, and once you run out, you can’t give any more orders. Unfortunately the playstyle the dev enforces results in the player’s role diminishing as the game progresses and their fleet grows, until eventually the game mostly plays itself. The game is overengineered, bloated, and the development drags on. I’ve lost count of how many skill system reworks there have been in the last decade. The dev is just fiddling at this point, and a lot of the systems he’s been trying to balance for years could just be removed entirely without anything of value being lost (ECM, capture points & command points, combat readiness, etc.).
